Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier for sales teams. B-tier for solo users.S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds.
